| 520 | 3 | |a Studies are underway to identify compounds that will, at cost-effective concentrations, inhibit scale and solids formation when added to the brine at the high-temperature (approximately 200°C) front end of the plant. The study reported here constitutes a preliminary, bench-test screening of 49 substances, the most promising of which will be examined later in on-line pilot plant studies. A variety of substances were tested, including both simple and polymeric alcohols, ethers, aldehydes, carboxylic acids, amines, amides, cellulose derivatives, and classes of materials such as detergents, surfactants, and coupling agents. An inorganic phosphate, KH₂PO₄, and a chelating agent EDTA, also were tested. In the present work the additives were mixed with hypersaline brine that had been acidified to pH 4.0 +- 0.3 and flashed to 1 atm, approximately 100°C, in the LLL Geothermal Field Test Apparatus near Niland, California. The rate of disappearance of dissolved silica from the treated brine was compared with the rate for untreated brine as a measure of the effectiveness of the additive. (JGB) | |
